Colour blindness is caused by recessive sex-linked gene carried by $X$-chromosome. So, in male, one recessive gene is sufficient for its expression, $i.e.,$ $|X^{C} Y|$ but female needs two recessive gene $|X^{C} X^{C}|$ for the expression of colour blindness.

Mother will colourblind with $A$ blood group and father normal with blood group-$B$ as $-i$

So, all the sons will be colourblind with $AB$ blood group..
